as far as I know it's unreal tournament 3 mod "Ball". Pic (http://www.gamespot.com/pc/action/unrealtournament2007/images/6210355/1/?tag=thumbs_below%3Bthumb;1), link (http://www.strategyinformer.com/pc/unrealtournament2007/mod/33863.html)We know that. The OP is interested in how the developers came up with the original idea which as we know started as a mod, was updated, added to, and is now a commercial game.

We were inspired by the atmosphere of Unreal, the environments of Tomb Raider, the HL2 gravity gun, and the simplicity yet beauty of Portal, and threw all of that together into a single game.

A nice mix :) I love the exploration feeling.

To me, this game remember me a bit "Exhumed" (played on a Saturn in 96)
